I thought they fixed the tire temp v. pressure issue?

Hi,

I thought the latest PS4 update 1.14 was supposed to fix the issue where the optimal tire pressure didn't match up to the green indicated optimal tire temp? GT3 tires seem fine but Semi-slicks still seem off. It feels like 29-31 psi (warm) is about ideal for lap times but the tire app shows blue or faint green at those pressures.
